摘　　要：提出了1套适用于轨道交通车辆主动径向系统的故障导向安全方案。针对系统架构中列车级控制器、车辆级伺服控制器、车载线路检测硬件、动作执行单元等层级均进行了故障导向安全方案的策略研究,特别优选了1套主动径向系统动作执行单元技术方案。由此进一步增强了主动径向系统的安全性,为主动径向系统的工程化运用提供了参考。A set of fault-oriented safety policy applied to active radial system for rail transit vehicle is proposed,which is implemented on each level of the system architecture,such as the train controller,vehicle servo controller,line detection hardware and execution unit.In particular,a set of motion execution unit technology for active radial system is proposed,which will further enhance the safety of active radial system,providing a reference for the engineering application of active radial system.
